Porcello, who is from New Jersey, told Hunter that he knew some people affected by Hurricane Sandy.

"He said, 'The money that you offered me, could you donate it to this organization for Hurricane Sandy?' " Hunter said Friday at Comerica Park. "That's the kind of guy Rick Porcello is. He freely gave me No. 48."

The Tigers announced that Porcello will wear No. 21, which he wore in high school.
